It’s all up 2 genetics and some times weather also goes into it

Definitely get that ph up , I try to always keep mine between 6.2 and 6.7. From the looks of your runoff none if them will need any food just yet. When you water use a higher ph like 6.8 to 7.0 to help bring the soil ph up.

Awesome. I think I’m gonna have a few different looking buds.

Watered/fed on 9/18; see post above. Ph was a bit low over all so I may be having some lock-out. Let me know what you think.
I can probably water/feed again on Saturday, maybe Friday. I will boost ph of in-going water to 6.9 to boost run-off ph.

So, my 4 Gold Leaf Feminized are 43 days above the dirt. I was planning on waiting until they were about 60 days old to flip the lights to 12/12. Probably still will.
My question is this: My 9 White Widow Auto-flowers are all in various stages of flower, and are also 43 days above the dirt. When I flip from 18/6 to 12/12 will it affect the Autos?

Please scroll up 8 posts.

You have lots of run off test posted but not sure which plant your talking about.
Oh my, gold leaf and white widow, two of my favorites 
Nope, autos will be fine with the switch to 12/12

Thanks!
You mean in the pictures?
Yes. Which plant is showing those symptoms or is it several. Ester and Sally would be most at risk. I wouldnt feed until your tds is around 700ish.

The plants in question are:
Norma
Zoe
Sandy
Mildred
Theresa
This is Mildred. Well on her way in flower. I thought this would be too soon for her to start consuming the nutes in the lower leaves.
I find that sometimes those old ones just die off, she knows they are just dead weight, not getting much light, doing any work and not contributing to the whole.

**** I need advice. You can call me crazy or stupid… I don’t care! After a watering with water ph’ed to 6.8, Ester had a Ppm of 2020 and a ph of 6.2. I flushed with water ph’ed to 7.5. The ppm’s dropped to 1480 but the ph dropped to 5.9??? So I flushed again with water ph’ed to 8.3; the ppm & ph dropped to the data listed above. I don’t understand how the ph keeps dropping! WTF? Am I not understanding something? My numbers were not wrong.

What water are you using to flush? Definitely make sure your ph pen didn’t go wacky.

I didn’t have RO so I used my well water. I added a little Cal-Mag to help stabilize the ph. I also used it in every other plant. So far, no other plants have any issues with it. Knock on wood.
I am going to put my eyes on them b4 bed. Hopefully there won’t be any surprises.
Yeah… I have calibration solution so I can test it with it.
